r T all whom it may concern Be it known that I, SonnN C. MoNBnRG, a

' citizen of the United States, residing at Leadville, in the county ofLake and State of Colorado, haveinvented new and useful Improvements. in-Air .Compressors or Pumps, of which the'following is a specifi cation.1 I

This invention relates to pumping devices, particularly to those of thecentrifugal type, and has for its object the provision of a novel formof.air..compressor or pump adapted for many uses and in which use ismade of a rotarywheel which sucks in the fluid at the center and whichis provided with radial p'zfssa 'eswhereby the fluid will be'forcedoutwar ly under the influence of centrifugal force and be subsequentlydeliv' ered to the place Where its use is desired.

An additional object is the provision of a device of this characterwhich will be simple in construction, easy to operate, efficient anddurable in service, and a general unprovement-in the art.

' With the above and other objectsand advantages in view, the inventionconsists in the details of construction to be hereinafter more fullydescribed and claimed, and illus gether by suitable bolts 12. j ,At itsupper and lower portions the frame carries attaching feet 13 whicharesuitably secured to the casing. It is ofcpurse apparent that thecasing of the device should be suitably mounted upon a base Formed atopposite sides ofthe "frame-1 1,

which is circular as. shown and which 1s provided with a circular]opening 15;, are extensions 16 ,which are formed hollow or rather whichare provided 'with vertically extending bores 17 each threaded at bothends. At eachside of the .irameis formed an opening or passage 18leading from the Obntral opening in the frame into the bore 17.

rim portion 25 havingteeth-like projections 26 thereon serving as vanesand also includes 7 other fluid.

lti sing'from the base 14 at opposite sides of the caslng 10, arebearings 18 and journaled through these bear-in s are shafts 20 and 21which pass through the frame 11 and one of these shafts is formed hollowand the other solid, the solid shaft extending into the hollow shaft andforming ajclosure for one end thereof. The hollow shaft is providedadjacent the end of the solid shaft with ports 22 which establishcommunicatlon between the hollow shaft and the in- .terior of the frame.i

Secured upon the hollow shaft and located within the frame 11, is .awheel indicated by the numeral 23 and this wheel includesa hollow hubportion 242 which provides an, annular chamber communicating with theports 22. This wheel. further includes spokes 27 which are formed withpassages extending therethrough and. through the reg-is. tering one ofthe teeth 26. These passages are tangential with respect to theperiphery of the chamber in the hollow hub, and com- Lounicate at theirinner ends with this chain'- GIZ ,7, f

The frame 11 is formed at each side with an inwardly extending flange 28which ter- 29. Secured to the flanges 29 and bearing against the sidesof the wheel aredeather or rubber packing rings 30.

In the operation of the device, when the, wheel is rotated by means ofasuitable drive pulley or the like 32 secured on either the shaft 20 or21, air or any other fluid will be sucked in through the open end of the1101- a low shaft and will pass through the ports low hub. As, the wheelis rotated centrifugalforce will cause the air to be forced outwardlythrough the passages 2-7 against th inner periphery of the frame 11. Theair Willof course pass rapidly along the inner wallof the frame anduponreaching The passages 18, will pass into the bores 17 Qi the extensions16, It will beobserved that any outlet pipes or hose may be screwed intothe threaded ends of the bores 17 for conducting the air or other fluidto the place where its use is desired. The teeth 26 serve as battles toFrom the foregoing description and a study of the drawings it will beapparent' L minates in an outwardly extending flange 22into the annularchamber within the holi prevent back flow of the air or that I have thusprovided a simply constructed and consequently inexpensiveeen trifugalpump device whereby air, anygas,

porting frame having an opening therein and provided at its sides withextensions formed with bores adapted for connection Jvith outlet pipes,said extensions being pro- 2o vided with passages communicating with thebores therein and with the interior of the frame, a hollow shaftextending through said frame and provided therein with. ports, andawheel secured upon 'said shaft and having ahollow hub communicatingwith said ports and including spokes formed with passages leading fromthe hollow hub to the" outer periphery of the wheel. 1

2. A device of the character described comprising a supporting base, acasing rising therefrom, a frame secured within said casing and having acircular opening therein, extensions at opposite sides of the frameprovided-nth bores, said frame being procating with the opening thereinand with the bore of the ad]acent extension, bearings rising from saidbase at opposite sides of the frame, a hollow shaft journaled throughone bearing, a solid shaft journaled through the other bearing andextending into the hollow shaft whereby to form a closure for one endthereof, a wheel secured upon the hollow shaft and disposed within saidframe, the wheel having a hollow hub providing an annular chamber, andthe hollow shaft being provided with ports communieating with saidannular chamber, said wheel further including a rim portion havinginclined tooth-like projections thereon, and the wheel further includingspokes each formed with a passage communicating with the annular chamberand extending to the outer periphery of the wheel, the bores in saidextensions providing means for attachment of discharge pipes.

In testimony whereof I afiix my si nature.
